☠️ Cueva de la Muerte – the deadly mercury tunnel Tucked away in the hillside is this former tunnel, once used to extract mercury, now known as the "Cave of Death." Poisonous gas (including mercury vapor) constantly escapes from within, making the cave extremely dangerous. A fascinating, yet threatening, site of geological and historical significance. Tip: Never enter! Even a few breaths in the tunnel can be life-threatening. Observe only from a safe distance and treat the area with respect.

The stalactite cave was rediscovered in 1911 after being forgotten. It is a 76 m long tunnel system that was created in the 18th century by mining work. You should definitely take a good flashlight with you when exploring the caves. Waterproof shoes are also recommended as the floor is one huge puddle.

𝗪𝗶𝗹𝗱𝗳𝗿𝗮𝘂𝗲𝗻𝗹𝗼𝗰𝗵 In the early days, the Wildfrauenloch was associated with the goddesses of the Celts. As a rule, these were holy places where homage was paid to these gods. Since then, many stories and legends have grown up around them. So also the legend of the wild woman in Baumholder: After the defeat of the Huns on the Catalaunian fields, they withdrew to Hungary. They are said to have left a Hun woman of unusual size and wildness in this area, also called "wild woman". Their weapons are said to have been a crooked Hun dagger and a mace. Their food consisted of berries, roots, herbs and the raw meat of slain deer, stags, boars and wolves, which they pounded tender between two stones. She was not only considered a bold robber, but also a scary cannibal. However, the men could not catch them even with combined strength. Because in the event of an attack - according to tradition - she simply closed her cave with a heavy boulder so that nobody could move it. Source: text information board

Not so easy to find from above. Over the take-off hill, take the narrow, winding path down! Lovely picnic spot with a view and a lovely story about the Fri-Fra Loch!
